摘要

采用超声波离子改性水滑石，并将其添加在等规聚丙烯材料中。运用X射线衍射仪技术（XRD）、傅里叶红外光谱（ATIR）、差示扫描量热（DSC）、偏光显微镜（POM）、扫描电镜（SEM）等方法测试表征了水滑石通过超声离子改性前后对等规聚丙烯材料结构的影响。结果表明，超声离子改性的水滑石能扩大水滑石层间距，促进和增加改性基团的插层率，能改善其在等规聚丙烯中的分散性，对等规聚丙烯起到明显的异相成核作用，细化其晶粒，同时能够增强和增韧等规聚丙烯材料。

Abstract

Hydrotalcite was modified by ultrasonicandion exchange method was added to isotaticpolypropylene (PP)materialssubsequently. X-ray diffraction spectra (XRD)

Fourier transform infrared spectroscopy (ATIR)

differential scanning calorimetry (DSC)

polarized light microscopy (POM)

scanning electron microscopy and other methods were used to characterize the effect of hydrotalcite on the structure of isotaticpolypropyleneby ultrasonicandion exchange method. These results indicated that the intercalation rate of modified groups can be promoted and increased

the dispersibilityofhydrotalcite in isotaticpolypropylenecan be improved by ultrasonic ion exchange method modified whichplays a distinct heterogeneous nucleation effecton isotaticPP

and the toughness of polypropylene material was simultaneously enhance by the refined grain.
